Always Kiss Moments

Castle’s face when he opens the door - he obviously has no idea who is there, but is ready with his nice-to-meet-you face and we get to watch his expression change as he comes to terms with seeing Beckett.
Castle’s breathing after she kisses him the first time. You can see the hesitation in his hand and hear it in his breathe. It’s fabulous!
Kate’s eyes as she says “And all I could think about was you.” They flick from his eyes to his mouth as she then says “I just want you.”
Her smile after the last kiss before grabbing her hand.
Kate biting her lip after grabbing his hand to lead him (we presume) to the bedroom.
Her hands on his face the whole scene and how that gesture is such a search for connection and closeness. It’s memorizing that person and cements the moment, let’s you hold it all in your hands for a moment. Hard to describe.

Ugh. The entire thing. But those specific details are just amazing.
